inotify_init1

SYNOPSIS

DESCRIPTION

inotify_init() initializes a new inotify instance and returns a file
descriptor associated with a new inotify event queue.
If flags is 0, then inotify_init1() is the same as inotify_init(). The
following values can be bitwise ORed in flags to obtain different
behavior:
IN_NONBLOCK Set the O_NONBLOCK file status flag on the new open file
description. Using this flag saves extra calls to fcntl(2)
to achieve the same result.
IN_CLOEXEC Set the close-on-exec (FD_CLOEXEC) flag on the new file
descriptor. See the description of the O_CLOEXEC flag in
open(2) for reasons why this may be useful.

RETURN VALUE

On success, these system calls return a new file descriptor. On error,
-1 is returned, and errno is set to indicate the error.

ERRORS

EINVAL (inotify_init1()) An invalid value was specified in flags.
EMFILE The user limit on the total number of inotify instances has been
reached.
ENFILE The system limit on the total number of file descriptors has
been reached.
ENOMEM Insufficient kernel memory is available.
